9 Claims.

My invention relates to mixing devices and its objects are, to create in copious quantities carbonated beverages or water without the necessity of the application of the usual attendant pressures; to avert the danger from the production and storage of possibly explosive mixtures due to sudden changes of temperature or confined pressures; to provide a cheaper and handier form of construction for the production of carbonated waters; to carbonate fresh fruit juices immediately upon their production from the fruit; to stabilize the production of effervescent mixtures and to prevent deterioration thereof,

. particularly when exposed to the air; to afford a better means for the dispensing and distribution of effervescent waters, beverages and medicines, and generally, without the necessity of employing expensive apparatus, to afford an effective and simple means for producing carbonization of fluids at the time and place desired.

As is well known, siphon bottles or containers of carbonated beverages are very susceptible to any substantial changes in temperature, and in order to guard against explosions and the spray-- ing of glass upon persons in their immediate vicinity, must always be kept at a'low temperature. With any rapid rise in temperature, the amount of pressure upon the walls of the closed receptacle is increased, and if such rise is continuedthe internal pressure will shortly'reach a point where an explosion will inevitably take place. Especially is this true where the contents of the bottle have been frozen, in which case great care should be used when such bottle is thawed. Should it be placed under the hot water faucet, or in the vicinity of a heater or stove, and the thawing not accomplished gradually, an explosion is likely to result. Each of the siphon bottles now in commercial circulation ordinarily carries a pressure well over a hundred pounds, and is therefore potentially a source of danger. Many accidents, according to the reports of industrial accident commissions, can be traced to this cause, and will continue to happen unless proper precautions are taken. Then again, in the case of any carbonated beverage contained in a bottle or other container, the gas therein contained tends to seep out with the passage of time, so that with the expiration of a few years after carbonization, there will be little or no effervescence upon the opening of the bottle..

With the operation of my improved device, however, there is no danger of explosion whatever. In the actual production of carbonated water at no time is it my purpose to confine the charged fluid in a closed receptacle. The desired carbonization I effect as needed, withoutthe application of the usual pressures, and without the use of high pressure tanks, metal capsules or the like. Through the use of my device, carbonated water is manufactured on the spot, and in the quantities desired. For immediate use it is especially designed to be used in dispensing beverages at a soda fountain or liquor counter,

where potable liqours are combined with effer vescent waters in the form of mixed drinks, and where it is very desirable to have at hand an unlimited supply of such waters. Being manufactured or composed as needed, there is no possibility of deterioration, or explosion.

Attention is hereby directed to the drawings in which similar numerals of designation refer to similar parts throughout the several views, and in which- Figure 1 is a perspective view of one form of my improved device, showing the same in its usual upright position;

Figure 2 is a plan view of the same;

Figure 3 is a horizontal section on line 3-3 of Figure 1, looking in the direction of the arrows;

Figure 4 is a horizontal section on line 44 of Figure 1, through the faucet there shown looking in the direction of the arrows;

Figure 5 is a perspective view of a modification of my invention;

Figure 6 is a perspective view of a modification of my invention showing the same in the form of a rectangular box;

Figure '7 is a longitudinal section of a magazine cap designed as a cover and filler for my improved receptacle; and

Figure 8is a section on line 88 of Figure 7 looking in the direction of the arrows.

Referring to the drawings, I preferably construct my improved apparatus of metal, glass, enamelware, clay products or other suitable material or substance upon which tartaric, citric or other acid bases have no deleterious effect. The main body 8 is constructed with the central septum .9, vertically disposed at right angles to the base I0 and dividing the chamber ll into dual compartments A and B, which are of like capacity and volume and extend the entire length of said chamber. At the top of the chamber 1 I, is located the dam plate I2, partially covering the same,'the function or purpose of said plate being to dam back or hold in check the fiuids contained in compartments A and B. Back of the dam plate I2, I locate the dual openings l3 and I4,

to permit the ready introduction of carbonated water producing substances.

Preferably near the top of my device, at the front thereof, for the purpose of evacuating the fluids therein contained in equal amounts, is located the nose or spillway I5, divided into two sub-compartments A and B divided by the common septum 9. At the bottom of each sub-compartment A and B are the orifices l6 and H, which are of equal diameter or open area in cross section and communicate with the compartments A and B respectively, and permit the discharge of their contents in equal amounts.

If desired, an additional dual outlet may be provided at the bottom of my device in the form of the faucet or valve l8, having substantially the same construction so far as concerns ducts or outlets as the nose 15, except for the valve closure or plug I9. As is obvious, this faucet or valve construction [8 could be substituted for the nose l5, or the apparatus provided with only one of these discharge openings and the other dispensed with.

In Figure 5, I have illustrated a modified form of my device, in which I have shown a single sheet of metal bent in the form of a wedge with the edges secured together at the line 20, the septum Pia. serving to divide the chamber Ila into two equal compartments C and D similar to compartments A and B of Figures 1-4, and the edges of said septum 9a being similarly attached.

In Figure 6, I have shown another modification in which the chamber II is of rectangular construction, having compartments E and F, septum 9B, and faucet or valve [8a similar to the construction shown in Figures 1 and 4.

In Figures '7 and 8, I have shown a magazine cap or cover 22 which may be employed for the commercial dispensing of carbonated water, and which adds to the utility and better and more efficient operation of my invention. Such cover is provided with the rotating handle 2! having secured thereto the rotating post 23' to the lower end of which, and at right angles thereto, is attached the arm 23 arranged to rest and move upon the plate 30, said plate being preferably soldered or welded to the septum El and to the inner wall of the main body cylinder 8, and acting as a dam plate in the same manner as plate i2 shown in Figures 1 and 2.

A tablet magazine 24, constructed to receive a supply of tablets of bicarbonate of soda 25 and a tablet magazine 26 constructed to receive a supply of tablets 27 of tartaric or citric acid, are attached to the inner wall of the cap 22, and each extend downwardly nearly to the floor 30 of said cap, a space being left under the lower end of each magazine to permit the egress of a tablet upon contact with the arm 23. As will be observed, the tablets are somewhat larger than the tablets 2?, although each tablet is of the same thickness. In the floor 3i], is the opening 28, which is of larger diameter than one of the tablets 25 and which is located in the path of the cup of the rotary arm 23, and permits the said tablet to descend therethrough into the chamber A upon being swept therein by said arm 23. In the floor also, is the opening 29 into the chamber B, which performs a similar office for the tablets 21. A groove 3i located near the edge of the cap 22 and shaped to engage with a corresponding groove in the cylinder 8, serves to keep the said cap in proper engagement with the compartments of said cylinder.

To operate my improved apparatus, I preferably first introduce through the aperture [3 into the compartment A a predetermined quantity of tartaric or citric acid and then add water in the proportion of 35 grains to 6 or 8 fluid ounces of water until said compartment is filled. I then introduce through the aperture I 4 into the compartment B a predetermined amount of bicarbonate of soda or other alkaline substance and then add water in the proportion of 40 grains t0 6 or 8 fluid ounces of water until the compartment is filled. These proportions may be varied in accordance with the amount of effervescence or carbonizaticn desired; preferably, however, I find that the best results can ordinarily be secured by the employment of parts of tartaric or citric acid to 9 parts of bicarbonate of soda, each being in adequate solution in its individual compartment.

Thereupon, upon the container being tilted, or the contents discharged through the outlets provided, equal measured amounts will be simultaneously discharged or permitted to flow into the drinking receptacle through openings I 6 and I1, said amounts beginning to mix immediately upon said discharge and continuing to mix upon reaching said receptacle, and to efiervesce and to release carbonic acid gas in copious quantities thereafter. As will be observed, the septum 9 effectually prevents the mixture of the two fiuids except as they actually come together after leaving the said spillway,

r/iy invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiment, as above set forth, is therefore to be considered in all respects as illustrative and not restrictive, the scope of my invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
